The correct option is a: True because indexing in arrays start with a zero.

Question 2:

The correct option is d. int scores[10]; This declares array of 10 integers.

Question 3:

The correct option is b. False. This is because arrays stored elements of the same datatypes stored in contiguous memory location.
